PAVEMENT.

SPECIFICATION forming part of Letters Patent No. 398,055, dated February19, 1889.

Application filed July 7, 1888. Serial No. 279,275. (No model.)

To all whom it may concern;

Be it known that I, J OHANNEDUARD KNOCHE, of San Jose, in the county ofSanta Clara and State of California, have invented a new and usefulImprovement in Pavements, of which the following is a. full, clear, andexact description.

This invention relates to pavements constructed mainly of hollow metalblocks or shells, which may either be left empty or be filled withconcrete or other material, and which are checkered 011 their uppersurfaces to prevent horses when traveling thereon from slipping, also togive the hoofs and calks of the animals a firm hold; and the invent-ionc011- sists in a novel construction of such a pavement and in acombination therewith of gutterblocks and flanged side supports to thepavement, substantially as hereinafter described, and pointed out in theclaims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 represents a view in perspective of one of the pavement-blocks.Fig. 2is an under view of the same. Fig. is a transverse section thereofupon the line 0c of Fig. 1. Fig. 4: is a plan view of a metal-pavedcarriage-way in part, with gutter and sidewalk in part, all inaccordance with my invention. Fig. 5 is a transverse sectional view ofthe same, and Fig. 6 is a view showing a modified construction of theflanged support which unites the arriage-way pavement with the gutter.

A indicates the carriage-way of the road, B its gutter, and one of thesidewalks in part.

Substantially similar pavement-blocks are used both for the carriagewayA and the gutter B. These blocks'D, which are hollow, are each in theform of a shell, closed on their tops but open below, and made of iron,steel, or other good and suitable metal. Said blocks D may be made ofany desired length, width, and depth, of parallelograinmic form, butwith their sides and ends of tapering construction, so that they are ofless area at theirtops than at their bottoms, and when laid side by Sideor end to end leave a tapering space in between them, which may besuitably filled in with earth or other material. In changeableclin'lates strips of wood, felt, or other yielding material may be laidin between the blocks to allow for shrinkage and expansion.

In every case the ground should be suitably prepared and leveled beforelaying the blocks, which in the construction of the carriageway arearranged side by side crosswise of said I form on the carriage-waysurface six raised portions, 12, of like area, which form a goodcheckered surface to preventhorses from slipping and to secure a goodhold for their hoofs and calks. To economize metal in the constructionof these blocks, and at the same time to give them increased strengthwhere more strength is required, they are made of reducingthicknessin adownward direction at their sides and greater thickness at their tops.This, in conjunction with the tapering form of the blocks, combines bothlightness with strength and a broad base and reduces the expense of theblocks.

To form the gutter B between the pavement of the carriage-way A and thesidewalk C, any number of. rows of the pavement-blocks D, which may, ifdesired, be differently grooved 011 their tops, are laid lengthwise ofthe gutter at any required depth, and combined with these or row ofgutter-blocks next to the carriage-way A is a metal flanged support, G,to the side of the carriageway pavement, and

which stands as high above-the surface of the gutter-block as the depthof the gutter, and is flush at its top, which is rounded, withthe outeradjacent row of blocks of the carriageway. This flanged support G (shown in section in Fig. 5) forms the edge of the gutter, where in a citythe horses stand, tramp, and

paw, and it is made of suitable strength to resist such wear and tear.Said support G, which is made up in sections of suitable length, isshaped or set sloping to bear against the outer sides of the outer rowof blocks composing the carriage-way, as shown in Figs. 4 and 5, saidsupport G or its several sections either being made with a base-flange,g, as shown in Fig. 5,01 with an overlapping anglepiece, 72, as shown inFig. 6, and serving to brace the gutter-blocks an d adjacent carriagewayblocks together, and in which Fig. I said support G is cast on andintegral with the 1 1 and metal flanged supports G, extending fromblocks D of the carriage-way ncxtto the gutter.

A pavement constructed as described will be strong, durable, andcomparatively noiseless, may readily be taken up and replaced to laydown gas, water, and other pi.pcs,including pipes for various electricwires; and if the ground on which the blocks rest be properly preparedand pressed there will beno settling of the blocks after replacing them.

Having thus fully described my invention, I

claim as new and desire to secure by Letters Patent- 1. In a pavementcomposed of metal blocks, the metal blocks D, of shell-likeconstruction, open at their base but having closed checkered or groovedtops and tapering downward]y-diverging sides of diminishing thick nesstoward their bases, substantially as specilied.

In a street or road having a carriage-way, A, gutter B, and sidewalk C,the carriage-way and gutter pavements each composedof metal shell-likeblocks D, constructed. as described,

the gutter-blocks up to the tops of the adj acent carriageway blocks andarranged to bear against the sides of the latter and to brace them andthe gutter-blocks, essentially as shown and described.
